using such a server as httpd (I assume that's a daemon) - Do you know if you can do basic "pop up" landing page like that of a captive portal in some ways? I'm looking to have a web page display when a user connects to the wifi hot spot I'm running on the wlan0 interface of the Pi while the eth0 interface is providing the connection. This webpage is already hosted on the www so I literally just need to have it pop up when a usr connects to the hot spot.

Do you know if httpd would do that and if so, perhaps any example that have been done on PiCore that you know of?
